Candlestick Patterns
Candlestick Patterns are a visual tool used in technical analysis to chart and interpret the price movement of a security, like a stock or bond. Originating from 18th-century Japanese rice traders, most notably Munehisa Homma, these charts offer a more intuitive and information-rich alternative to simple line graphs. Each “candlestick” represents the price action over a specific period—be it a day, an hour, or even a minute. By displaying the open, high, low, and close prices, candlesticks provide a quick snapshot of the battle between buyers (bulls) and sellers (bears). When these individual candles form recognizable sequences, or patterns, some traders believe they can predict future price direction. For a value investor, while not a primary tool, understanding these patterns can offer valuable insights into market sentiment and the psychology driving short-term price fluctuations.
Reading a Single Candlestick
To decipher the patterns, you first need to understand the language of a single candle. Each one tells a story with two main parts.
The Body
The thick, rectangular part of the candlestick is called the “real body.” It represents the range between the opening and closing price for the period.
- A green (or white) body means the closing price was higher than the opening price. Bulls were in control!
- A red (or black) body means the closing price was lower than the opening price. Bears won the day.
The size of the body also matters. A long body indicates strong buying or selling pressure, while a short body suggests little price movement and consolidation.
The Wicks (or Shadows)
The thin lines extending above and below the body are the wicks (also called shadows or tails).
- The upper wick shows the highest price the security traded at during the period.
- The lower wick shows the lowest price it traded at.
Long wicks suggest that prices fluctuated significantly during the period before closing near the open, indicating a battle between buyers and sellers that ended in a stalemate.
Common Candlestick Patterns
Patterns are formed by one or more candlesticks and are typically classified as bullish (indicating a potential price rise), bearish (indicating a potential price fall), or neutral. Here are a few famous examples.
Bullish Patterns
These patterns suggest that an uptrend may be starting or continuing.
- Hammer: A single candle with a short body, little to no upper wick, and a long lower wick. It looks like a hammer and often appears after a price decline, suggesting that buyers stepped in to push prices back up from their lows.
- Bullish Engulfing: A two-candle pattern where a small red candle is followed by a large green candle whose body completely “engulfs” the previous red candle's body. It signals a powerful shift from selling to buying pressure.
Bearish Patterns
These patterns warn that a downtrend might be on the horizon.
- Shooting Star: The opposite of a hammer. It has a short body, a long upper wick, and little to no lower wick. It typically appears after an uptrend and suggests that sellers overpowered buyers, pushing the price down from its highs.
- Bearish Engulfing: The evil twin of the bullish version. A small green candle is followed by a large red candle that completely engulfs it, signaling a potential reversal to the downside.
Reversal/Indecision Patterns
- Doji: This is a special candle where the open and close prices are virtually identical, resulting in a very thin (or nonexistent) body. It resembles a cross or plus sign and signals indecision. Neither buyers nor sellers could gain control. It often precedes a trend reversal.
A Value Investor's Perspective on Candlesticks
Let's be clear: As a value investor, your decisions should be rooted in fundamental analysis—understanding a business's health, its competitive advantages, and its intrinsic value. You buy great companies at fair prices, not by reading the tea leaves of a price chart. However, dismissing candlestick patterns entirely is like ignoring the emotional state of the person you're negotiating with. In the market, that person is the famously manic-depressive Mr. Market, and his mood swings create opportunities. Candlesticks are a fantastic gauge of his current mood. Think of it this way: Your deep research identifies a wonderful company that is significantly undervalued. You've decided to buy. Now, looking at the chart, you see a “Hammer” or a “Bullish Engulfing” pattern forming after a long price decline. This could be a signal that Mr. Market's pessimism is finally exhausting itself. Using this pattern as a trigger for your already-justified purchase can help improve your entry point, potentially preventing you from buying just before one last stomach-churning drop. Bottom Line: For the value investor, candlestick patterns are not a crystal ball. They are a supplementary tool for gauging market sentiment and refining the timing of your entry and exit points. Always let fundamental value lead the way; let the candles simply light the path.
